This helps to answer my questions on total inventory of radiation at Fukushima. That will present a worst case scenario of release.

stock: I have reviewed and this is a great resource. I asked a further question related to MOX which I think will show much worse ending product of spent fuel due to more neutrons flying around and a hotter burn rate. Will advise if I obtain data.

now, a good estimate of total radiation inventory at Fukushima may be calculated. I will do so, busy on spring projects, it may take a while.

--------------------------------------------- I was asked to respond to your question.The NRC does not track the isotopic inventory in each spent fuel assembly at nuclear power plants. The following is a link to a public document titled “Characteristics of Potential Repository Wastes”:

It contains physical, isotopic, and thermal characteristics of all type of commercial spent nuclear fuel assemblies. For example, in the middle of Table 2.4.13 on Page 2.4.17, the most dominant (i.e., >1%) isotopes, in terms of curies/Metric Tons of Initial Heavy Metal (MTIHM), for a typical Pressurized Water Reactor (PWR) spent fuel assembly enriched up to 4.42%, burned up to 40,000 MWD/MTIHM, and cooled for 10 years are shown. These numbers are still valid to date. The number for each isotope should be multiplied by 0.45 MTIHM/assembly, which is a typical number for a PWR assembly, in order to obtain the isotopic inventory in a single PWR fuel assembly.Maureen Conley

I am become death, destroyer of worlds Here is a short clip of Oppenheimer and his famous quote above. A reader has suggested the the strange head twist (at 14 seconds in) as he begins his statement of I am Become Death is actually the devil entering his body. It sure is odd. And look at his face, the stress, the introspection, the resignment.

Here is a long documentary, over 1 hour, on The Day After Trinity One commenter stated----

I wish I could have told Dr. Oppenheimer: - "Thank you for what you have done for us and the burden you carry for your discovery. Now let us share the weight of your discovery and act responsibly for the future of the human race. Your efforts are not to be feared or demonized, but praised for the courage it took to continue forward. Whether we persevere or﻿ destroy ourselves is in our hands and you should bear no guilt for what you have accomplished."

I don't think I can be quite so encouraging or forgiving. Many of these scientists operate out of ego, trying to play God with matter. They do bear the burden of the evil they have unleashed on mankind. I haven't reviewed this video at this time, 27 minute interview with Oppenhiemer
